mhattingpete/claude-skills-marketplace
Claude Skills Marketplace is a curated collection of Claude Code plugins for software engineering work. It is organised as a marketplace repository with a .claude-plugin/marketplace.json manifest at the root and several plugins beneath it, each with its own plugin.json manifest, skills and, where relevant, agents. Skills here are model-invoked capabilities rather than slash commands: each is a SKILL.md file with YAML frontmatter carrying a name, description and metadata, followed by detailed instructions and optional supporting scripts, templates or reference files, and Claude decides from context and the description when to load one. Agents are separate specialised Claude instances defined by an AGENT.md file; they run with their own context and can use a model chosen for their task. The engineering workflow plugin contains a plan-implementer agent plus skills for feature planning, git automation and pushing, implementing review feedback and fixing failing tests. The visual documentation plugin adds skills that generate architecture diagrams, dashboards, flowcharts, technical documents and timelines, with a companion examples file. The productivity skills plugin covers auditing code, documenting an existing codebase, analysing conversation and usage patterns, and bootstrapping new projects. The code operations plugin handles direct code manipulation: Python code execution with example scripts, code transfer using a line-based insertion script, bulk refactoring and file analysis. A separate execution-runtime directory provides the code execution environment those skills rely on, consisting of an importable API library, a FastMCP server and a one-command setup script. The repository is also published through the Smithery skill registry. It is aimed at developers who already run Claude Code and want a ready set of reusable, automatically triggered capabilities for planning, review, testing, documentation and refactoring instead of writing each skill definition themselves.
